CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 575,166, dated January12, 1897. Application filed June 4, 1896. Serial No. 594,296. (Nomodel.)

`T all wir/0717, t may concern.-

Be it known that I, GEORGE D. PETTINGELL, a citizen of the UnitedStates, residing at .Ietferson, in the county of Greene and State ofIowa, have invented certain new and useful Improvements in AutomaticCar-Couplers, ot which the following` is a specification.

This invention relates to car-couplers, and particularly to an automaticcoupler adapted to oscillate vertically or transversely in accordancewith the movement of the cars it couples.

The object of the invention is to provide V an automatic coupler makinga rigid connection between the cars and adapted to hold thecoupling-link immovable between the ears until the latter are uncoupled.

A still further object of the invention is to provide a car-coupler ofsuch novel and peculiar construction that the coupling-link is heldrigid and at the same time adapted to be oscillated vertically andtransversely in accordance with the movement of the cars.

The invention consists in the novel construction and arrangement ofparts, as will be hereinafter fully described, and set up in the claims.

In the accompanying drawings, forming part of this application, Figure lis a longitudinal section of a draw-bar having my invention applied.Fig. 2 is a plan View of Fig. l with the top of the draw-bar removed andthe slotted cover or cap` also removed, showing the coupler open indotted lines. Fig. 3 is an inverted plan view of the bottom of the cup.Fig. 3 is a top view of the cover or cap. Fig. 4: is an inverted planview of the inclosing ring with its bottom removed. Fig. 5 is a frontelevationof part of a car-front, partly broken away, with thecoupling-pin raised and the coupler in position to receive a link. Fig.6 is a cross-section of the inclosing ring, showing the cup inelevation.

The same numeral references denote the same parts throughout the severaliigures of the drawings.

The draw-bar l is of the hollow form, with daring jaws, and having aremovable top 2. In the hollow of the draw-bar is inserted a ring 3,having a lateral inwardly-extending flange 4, a removable bottom 5, acut-out 6 formed by cutting a portion ofthe ring away, and pivot-lugs 7upon the inner side of said lateral flange.

Within the ring 3 is houseda cup S, having upon its bottom V- shapedprojections 9, which rest on the bottom 5 of the ring 3, allowing thecup free vert-ical oscillating or vibrating movement in accordance witha like movement of the cars. The cup has a cap or cover l2 and a fiange10, which engages the lugs 7, whereby the cup is poised in the ringpivotally between the said lugs 7 and the projections 9 and is free toturn or oscillate transversely in accordance with such action of thecars upon the coupling-link 13, the latter having .a circular head let,which passes through the cutout 6 in the ring and a slot l5 of the cup Sinto the latter.

Inside of the cup 8, upon the bottom, is formed rigid therewith asemicircular jaw 16, and a semicircular dog 17 is pivoted at 1S to thebottom of the cup. One free end of the dog has an arm 18a, provided witha hole I9 for the coupling-pin 20, and the other free end is engaged bythe link-head 14 to inclose the latter between the said jaw and dog andto bring the coupling-pin hole 19 over a similar hole 2l in the bottomof the cup, whereupon the pin is dropped and the coupling completed. Itwill be observed that in normal position the end of the coupling-pinrests upon the bottom of the cup, and as the link is pushed home againstone end of the dog the other end of the latter will carry the pin intothe hole 2l.

The cap or cover l2 has a slot 22 for the arm 1S, and the coupling-pinis lifted bya chain 23, attached to a hand-bar 24, which can be operatedfrom the topor either side of a car. A spring 25 is fixed upon aprojection 26 in the rear of the ring 3 and acts as a cushion for thecoupling device.

I-Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an automatic car-coupler, the cup pivoted in a draw-bar tooscillate transversely and vibrate vertically, a jaw in the bottom ofthe cup, and a dog pivoted in the bottom of the cup and carrying acoupling-pin, said dog being operated by the link to lock the dog to IOOthe cup and the link-head between the jaw and dog, as set forth.

2. In an automatic car-coupler, the cup having a fixed jaw and a pivoteddog, pivot projections upon the bottom of the cup, combined with a ringsurrounding the cup and having pivot-lugs whereby the cup is held in thering upon the said projections and lugs, as set forth.

3 In an automatic car-coupler, the combination of the cup having a jawintegral with its inner bottom, a dog pivoted in said bottom andcarrying a coupling-pin, a removable slotted cover for the cup, andpivot projections on the under side of the cup-bottom, with the flangedring surrounding the cup
